IRONING-MACHINE.

Specification of Letters Patent.

. Patented Mar. 30, 1915.

o all 'whom it may concern.'

Be it known that I, DANIEL M. Coornu, of Rochester, in the county of Monroe and State of New York, have invented certain new and useful Improvements in Ironin Machines; and I do hereby declare the fdllowing to be a full, clear, and exact descri tion of the same, reference being had to t e accompanying drawings, forming a pai't of this specification, and to the reference-numerals marked thereon.

The present invention relates to improveineiits in ironing machines, of the articular type embodying a pair of rotatab e ironing rolls, one arranged to be moved into and out of engagement with the other, and it has for its object to provide an improved construction and arrangement of parts which will enable the more ready operation of the machine, permitting perfect control, and easier action of the arts.

A farther olijeet of my improvement is to provide a simple and improved means for enabling the adjustable` roll to be moved toward and from the other roll by fluid pressure.

To these and other ends the invention consists in certain improvements and combinations of parts, all as will be hereinafter more fully described, the novel features being pointed out in the claims at the end of the specification.

Fig. 10 is a similar View, with the valve closed.

Similar reference numerals throughout the several figures indicate the same parts.

The invention, as illustrated in the present embodiment, comprises a main supporting frame 1 having a base 2. Suitably mounted in the frame are the ironing rolls 3 and 4 arranged above and below one another respectively, the upper roll being fixed against bodily vertical movement, while the lower roll is arranged to be moved into and out of engagement with the up er roll, in a mannei' to be described resent y. The roll 3 is carried by the shaft 5 to which is secured a pinion 6 and a ear wheel 7, while the roll 4 is carried b t e shaft 8, one end of which is sup orte in a suitable bearing pivoted in the rame at 9. The shaft 8 is provided with a pinion 10 for engagement with the aforementioned pinion 6 when moved vertically into en agement therewith, as shown in Fig. 1. 'l ie gear wheel 7 is operated from a pinion 11 fixed. upon the hollow` shaft 12, the latter having keyed thereto a pulle 13. Loosely mounted on said hollow sha t 12 is a pulley 14, and 15 is a loose pulley mounted on the bearing 16, as shown in Fi 4. Belts 17 and 18 running in opposite irections are arranged for cooperation with the pulleys just described, one of said belts being enga ed with the fixed pulley and the other of said belts being in engagement with a loose palle The position of the belts is conti-olle a belt shifter including arms 1D and 20 w iich are mounted on the rod 21, the latter being operated in a manner that will present y e made clear.

The vertical movement of the lower ironing roll is preferably effected by fluid pressure controlled devices, comprising in the present embodiment a cylinder 22 within which travels a piston 23, the latter having pivotod thereto a connecting rod 24 which is pivotally secured at its upper end to the inks 25 and 26, and to the yoke meinher 27. The link 25 is pivoted to the supporting frame and the link 26 is in turn ivotally connected to the upwardly exten( ing rod 28, which at its upper end supports the bearing 20 for the lower ironing roll 4, and to the supporting link pivotally mounted on the support 31, the latter being held Within the frame in anyv suitableV manner, asglby. means of a bolt 32. The yoke member 27" carries a vertical rod 33 movable through an opening in a guide 34, which may be heldin the framein any suitable manner, a' spring' '35 being arranged on the rod 33 anddisf p posed between the guide 34 and the collar 36.*'A The purpose ofthis. is to prevent sudden jar of thepartsupon the downward move-l ment of the piston when the pressure is' released, the spring. 35 serving to retard vsuch movement and to prevent the piston' from comin -too violently in Contact with the bottom o the cylinder. Upward movement of the piston is effected by a fluid under pres# f sure, and preferably by means of compressed atmosphere to air, which is admitted to the cylinder in anyfif suitablelmanner from the pipe 37, and in the present embodiment, this is accomplished by a trans- V passage* 41 leads from the'valve 38 tothe cylinder means of a rotary valve 38 havin verse port'39 'and a by-pass 40.

while a second passage 42 is connected to the I ernilt the pressure vto beexhaustedfrom tli closed, at-which time the passage is'connected With'passagel41 by means rvof the bypass 40,`as shown in Fig: 3. When the valvev "1s turned, as will hereinafter be described,

` 'into more intimate engagement.i.-To this end, the piston 23 carries a downwardly projecting pin 43 of somewhat less' diameter the passage 42vis closed'andxthe portf 39 opens communication .'Withipassage 41, per-` mitting the compressed air to enter and to" raise the piston.v It is 'desirable to limit the Y 4 admission of movement-'of t pressure during the initial e piston, so' tliatu'the lower ironing roll may beraised slovvlyuntil jit is in contact with 'the upper rollg-after `which full pressurecan be applied'toffQL-.the rolls than the passage 41, and provided with a tapered extremity 44. Thus, when the valve is first opened, only a comparatively Vsmall amount of pressure can enter the cylinder,

'opening being restricted by the position ""Of -the'pin 43, and as the piston moves upto Wardly, vthe tapered portion 44 permits the opening'to be graduallyenlarged, until full pressureis admitted and the rolls are held 1n engagement as' long as the valve remains open. The cylinder 22 is mounted on the aforementioned support 31, as shown in Fig.

3, said cylinder bein provided with the neck 45 to. which attac ed the valvecasin'g 46.' The valve is -suitably attached to the rotary stem 47,' -to the outer end of which is se'- cured an arm .48 having` a yoke 49 at itsvv lower end. A shaft 50 is suitably journaled in the extension 51V and carries a crank arm 52, the latter being qprovided with a 'crankpin', 53 frorpfengagement with the yoke e cylinder when the valve is' TheQshat-O' carries'atfits opposite end the pinion 54, which is arrangedto be engaged ya gear segment 55 flxedly mounted o n the hollow shaft', or operating member 56. The v vlatter has fixed thereon al treadle 57. The*v lower roll 4 being normally out of engagement with the upper roll, Whenit is desired to'move it upwardly intoA engagement, theV treadle 57 is operated so as jto effect opening of the. valvef38 and admit pressure to tbe4 cylinder; `Upon releaseof the treadle, the

valve i'sfreturned Ato its normal closed position by means'ofla spring 58 which acts upon a-rod 59, the latter' being connected to the gear. segment 55,-as shown in Fig. 2.

. I have also provided a simple means for effecting reverse movement of the ironing gare' journaled in a block 66, which is piv otally su ported o'n a transverse post 67 so as to ena le it to be adjusted to permit' the parts to be lined up properly upon the oor when the machine is set in position. The

'block 66 is held in'adjusted position by means of a suitable bolt 68 passing through the upper slotted portion 69 and engagin 'in the extension 5l of the support 31. he treadles 57 and 65, previously mentioned, are designed'to be engaged by the foot of the operator when in standing position.

To operate a machine of this characterin 4one position for a long period is quite' tiresome, andit is desirable `to provide acon- Avenient means for enabling the operator to control themachine when sitting down. To

this end, supplemental treadles 69 and 70k are `provided, which are operatively connected to the treadles 57 and 65, respectively, as shown in Fig. 5, in which 71 is a-gear segment formed on the treadle and engaging a corresponding gear segment 72 on the treadle 65. The arrangement and position 'of the tread1es'69 and70 is such that they can read, ily be engaged by an operator when sitting on a stool, and the depression-of eitherone of said treadles effects thesame operation of to raise the lower ironing roll, or to .reverse 1f, the machine as the treadles 57 and 65, either f the movement of the ironing rolls. vThe outer ends of the o erating members l are journaled in bearin a casting provide with the feet 74 by 3, constituting part of-` Vwhich'it may be attached to the Hoor, as seeny ment of said member comprising a rod oper-v atively connected thereto and to ak piston, aVv
